[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0048] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0049] For the convenience of description, spatial relative terms can be used herein to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0050] In order to solve the technical problems that the power line is prone to breakage and other abnormalities during long-term twisting in the prior art, the application provides a tower fan which can reduce damage caused by the torque of the rotation of the tower fan body to a certain point of the power line, thereby improving the service life of the power line.

[0051] Figures 1 to 9 A tower fan provided by the application includes a base 1, a rotating disc 2, a wire passing shaft 3, and a power line 4. The base 1 is provided with a power line passing port 11 for connecting with an external socket through the power line 4. The power line passing port 11 can also be provided with a power line 4 interface, and the power line 4 interface can be detachably connected with the power line 4 at both ends. The rotating disc 2 is rotatably connected to the base 1, and a mounting cylinder 21 is protruded from the side of the rotating disc 2 away from the base 1. The mounting cylinder 21 is provided with a mounting cavity 22 penetrating through the rotating disc 2 and the mounting cylinder 21. A wire shaft is connected to the base 1 and penetrates through the mounting cavity 22 to be rotatably connected with the rotating disc 2. The wire passing shaft 3 is provided with a wire passing hole 31. The power line 4 penetrates through the wire passing hole 31 in a spiral shape, and one end of the power line 4 extends out of the wire passing hole 31 at one end of the base 1 and is connected with the power line passing port 11, and the other end extends out of the wire passing hole 31 at one end of the rotating disc 2.

[0052] In this application's technical solution, the base 1 is provided with a power cable port 11 for passing a power cable 4 or placing a power interface. A turntable 2 is connected above the base 1, and the turntable 2 can rotate relative to the base 1. A cable guide shaft 3 is provided directly between the turntable 2 and the base 1, and a cable guide hole 31 is formed on the cable guide shaft 3. The power cable 4 connected to the turntable 2 passes through the cable guide hole 31 in a spiral shape. When the turntable 2 rotates, the spiral power cable 4 can adapt to bending and torsional stress to a certain extent, making it less prone to breakage or damage. This solution reduces the damage caused by stress concentration at a certain point on the power cable 4 due to the torque generated by the rotation of the turntable 2, thereby improving the service life of the power cable 4.

[0053] Optionally, the power cord 4 passes through the wire hole 31 to the power wire port 11 along the spiral tangential direction. This method allows the power cord 4 to smoothly distribute stress to the spiral line when the turntable 2 rotates, thereby reducing the damage caused by excessive stress on the power cord 4 at the port of the wire hole 31.

[0054] like Figures 2-3 As shown, in the technical solution of this embodiment, the end of the mounting cylinder 21 facing away from the turntable 2 is provided with a first blocking plate 23 and a first limiting boss 24. The first blocking plate 23 and the first limiting boss 24 are spaced apart and form a first wire passage groove 25. The power cord 4 passes through the first wire passage groove 25. The end of the first limiting boss 24 facing away from the turntable 2 is provided with a first limiting hole. A first limiting member 51 passes through the first limiting hole so that the first limiting member 51 is located on the side of the power cord 4 facing away from the turntable 2.

[0055] After the power cord 4 passes through the cable hole 31, it enters the first cable groove 25. The first limiting boss 24 and the first blocking piece 23 are located on both sides of the power cord 4 to limit its movement. The first limiting member 51 can be a screw, with the screw head located above the first cable groove 25 to prevent the power cord 4 from coming out from above the first cable groove 25. This design can confine the power cord 4 within the first cable groove 25, preventing excessive swinging of the power cord 4 during use, and preventing it from becoming tangled or worn over time.

[0056] like Figure 4 As shown, in the technical solution of this embodiment, the base 1 is provided with two second blocking plates 12, which are arranged opposite each other at a distance, and the gap between the two second blocking plates 12 forms a second wire passage groove 13; the power cord 4 passes through the second wire passage groove 13 and extends along the second wire passage groove 13 to the power wire passage port 11; the base 1 is provided with a second limiting member 52 on one side of the second wire passage groove 13, so that the second limiting member 52 is located on the side of the power cord 4 away from the base 1.

[0057] After the power cord 4 passes through the cable hole 31, it enters the second cable groove 13. Two second blocking plates 12 are located on both sides of the power cord 4 to limit its movement. A second limiting boss is set on one side of the cable groove. The second limiting member 52 can be a screw, with the screw head located above the second cable groove 13 to prevent the power cord 4 from coming out from above the second cable groove 13. This design can confine the power cord 4 within the cable groove, preventing excessive swinging of the power cord 4 during use, and preventing it from becoming tangled or worn over time.

[0058] like Figure 2 As shown, in the technical solution of this embodiment, the turntable 2 is provided with a connecting protrusion 6 at one end near the base 1, the connecting protrusion 6 is provided with a slot 61, a ball bearing 62 is rotatably connected in the slot 61, and the ball bearing 62 abuts against the base 1.

[0059] In use, torque is applied to the turntable 2, causing the balls 62 in the slots 61 to rotate, thus achieving relative rotation between the turntable 2 and the base 1. This method significantly reduces friction (which can also be further reduced by injecting lubricant into the slots 61), thereby improving the operating efficiency of the turntable 2 and reducing energy loss. This not only reduces wear but also extends service life. Because the contact between the balls 62 and the bearings is very uniform during rotation, stable rotation is maintained, reducing errors caused by uneven friction. Since the balls 62 provide continuous support during rolling, the movement of the turntable 2 becomes smoother, reducing vibration and noise. Especially at high speeds, the balls 62 effectively distribute pressure, reducing imbalance in the turntable 2.

[0060] like Figure 7 As shown in the technical solution of this embodiment, a drive unit 7 is provided above the turntable 2. The drive unit 7 includes a drive motor 71, a drive gear 72, and a fixed gear 73. The drive motor 71 is located on the turntable 2 and is used to provide torque to the turntable 2. The drive gear 72 is located at the output end of the drive motor 71. The fixed gear 73 is sleeved on the periphery of the thread shaft 3 and connected to the base 1. The fixed gear 73 and the drive gear 72 mesh with each other.

[0061] In use, the drive motor 71 rotates, which drives the drive gear 72 to rotate. The fixed gear 73 is fixed relative to the base 1. When the drive gear 72 rotates, under the action of gear meshing, the drive gear 72 will revolve around the fixed gear 73. Since the drive motor 71 is fixed relative to the turntable 2, the turntable 2 will also rotate relative to the base 1 when the drive gear 72 revolves around the fixed gear 73.

[0062] like Figures 5-6As shown in the technical scheme of the embodiment, a rotation-stopping end cover 8 is inserted into the bottom of the base 1 into the mounting cavity 22, a first rotation-stopping hole 81 is arranged in the middle of the rotation-stopping end cover 8, the wire passing shaft 3 is inserted into the first rotation-stopping hole 81, and a plurality of first rotation-stopping pieces 82 are arranged around the hole wall of the first rotation-stopping hole 81.

[0063] The rotation-stopping end cover 8 can prevent the wire passing shaft 3 from rotating, so that the wire passing shaft 3 is fixedly connected with the base 1, and the rotation-stopping pieces can increase the friction between the wire passing shaft 3 and the rotation-stopping hole. In operation, the rotating disc 2 rotates, and the wire passing shaft 3 is stationary relative to the base 1 under the action of the friction between the wire passing shaft 3 and the rotation-stopping hole.

[0064] As shown in the technical scheme of the embodiment, a rotation-stopping end cover 8 is inserted into the bottom of the base 1 into the mounting cavity 22, a first rotation-stopping hole 81 is arranged in the middle of the rotation-stopping end cover 8, the wire passing shaft 3 is inserted into the first rotation-stopping hole 81, and a plurality of first rotation-stopping pieces 82 are arranged around the hole wall of the first rotation-stopping hole 81. Figure 8 The rotation-stopping end cover 8 can prevent the wire passing shaft 3 from rotating, so that the wire passing shaft 3 is fixedly connected with the base 1, and the rotation-stopping pieces can increase the friction between the wire passing shaft 3 and the rotation-stopping hole. In operation, the rotating disc 2 rotates, and the wire passing shaft 3 is stationary relative to the base 1 under the action of the friction between the wire passing shaft 3 and the rotation-stopping hole.

Figure 5 The rotation-stopping end cover 8 can prevent the wire passing shaft 3 from rotating, so that the wire passing shaft 3 is fixedly connected with the base 1, and the rotation-stopping pieces can increase the friction between the wire passing shaft 3 and the rotation-stopping hole. In operation, the rotating disc 2 rotates, and the wire passing shaft 3 is stationary relative to the base 1 under the action of the friction between the wire passing shaft 3 and the rotation-stopping hole.

[0066] As shown in the technical scheme of the embodiment, a rotation-stopping end cover 8 is inserted into the bottom of the base 1 into the mounting cavity 22, a first rotation-stopping hole 81 is arranged in the middle of the rotation-stopping end cover 8, the wire passing shaft 3 is inserted into the first rotation-stopping hole 81, and a plurality of first rotation-stopping pieces 82 are arranged around the hole wall of the first rotation-stopping hole 81.

In operation, the rotating disc 2 rotates, and the wire passing shaft 3 is stationary relative to the base 1 under the action of the friction between the wire passing shaft 3 and the rotation-stopping hole.
